wlan-ui is a very small Linux GUI tool for connecting to wireless
networks. It is written in perl, and is a basic example of using perl
with Gtk and Glade. There is also some simple process handling
(forking off a process, collecting output, killing the process if
cancelled). You can find the documentation in the wlan-ui POD documentation. Download the
script from the wlan-ui sourceforge
